(Oh I am talking degrees C, not F)
I have read that the betta fish likes temperature between 24 and 27 (C).
Of late I have done spot checks and found it up at 29. It is summer here and so it is to be expected that things are HOT.
We are about to go away for a while and I don't want to come back to a dead fish. Especially as I just got him.
The pump is making a bit of heat - 2 Watt water pump.
But I have been told it must be running for the aerobic filter to work.
He is in one of those aquasonic tanks holding about 4 Litres of water.
What are the options to not come home to a dead fish?
